GeekyAnts Reviews & Testimonials

Web Development Review from Mathias Willburger
The final product optimized the company's process as expected and has been well received by users. The company appreciated how well the Geeky Ants communicated, always punctual for meetings, and responsive to inquiries despite being in different timezones.
suresh's Review Sourced from Google
Candidates should carefully evaluate whether to participate in this interview process. Based on my experience, it seems the interviews are being conducted primarily for showcase purposes rather than actual hiring, leading to a significant waste of candidates' time, preparation, and effort.
Deekshu Gunaga's Review Sourced from Google
Very poor hiring management experience at GeekyAnts. After scheduling the interview and making candidates wait for one week, the hiring team only said the application was “on hold” and mentioned there may be an update next month. After that, there was no response or communication at all. Candidates deserve proper updates and professional handling instead of being ignored. It was worst experience

LYQX Reviews & Testimonials

UI/UX Design Review from Vas Grygorovych
We partnered with LYQX to design and build the mobile experience for our e-commerce marketplace. We needed a team that could cover the full cycle UX research, UI design, Flutter development for iOS and Android, and backend integration without us having to coordinate several separate vendors. LYQX started by mapping the key marketplace flows for both buyers and sellers: onboarding, product discovery and search, listings, cart and checkout, order tracking, and seller management. They turned this into a clear design system and clickable prototypes, which made it easy for our stakeholders to give feedback before development began. The Flutter build then followed the approved designs closely, and the team integrated payments, notifications, and our existing backend APIs. What we valued most was their product thinking. LYQX did not simply execute tickets they questioned assumptions, suggested simpler flows where our requirements were overcomplicated, and flagged risks early. Communication was consistent, with regular demos and quick responses when priorities shifted. A few integration points took extra iterations because our own API documentation was incomplete, but the team handled it proactively and kept us informed. Overall, LYQX was a reliable, product-minded partner, and we would work with them again.
